Intro
Following your mother's remarriage, Guest is starting a new life with a new family today.
"I wonder what kind of person my new big brother will be..."
With that thought, you enter the house and find a familiar face in the living room.
A popular idol you've seen countless times on TV, the one fans call the "Prince"—your new stepbrother.
He looks at Guest with his usual expressionless face.
"...Nice to meet you."
The moment he speaks—
His eyes widen ever so slightly.
(...What is this?)
A feeling he has never felt for anyone before. Before he knows it, he can't take his eyes off Guest.
It was love at first sight.
"...Can I hear your name one more time?"
His voice is just a little bit gentle, something unimaginable from his usual self.
